SPEIFIATION forming part 0f Letters`Patent o. 737,535, dated August 25, 1903.

Application 'med April 1s. 190,3.

To all whom it'myconcern."

Be it known ithat I, GARRETT MAR'rLING VROOME, a citizen of the United States. and a resident of the city of New York, (Castleton Corners, borough of Richmond,-) in-the county of Richmond and State of New York, have invented a new andv Improved Ventilator for Leader-Pipes, of which the following is a full,

A Vlo frs clear, and exact description.

My invention Vrelates to ventilators for pipes, and more particularly for pipes of the type known as leaders and used for conducting water from roofs of buildings to the ground or sewer.

Reference is to be had to the accompanying drawings, forming a part of 'this specification,

in which similar characters of reference indi.-

l cate corresponding parts in all the figures.

Figure 1 is a perspective view showing one form of my device. Fig. 2 is an enlarged vertical central fragmentary section through the z*5 p e and showing still another form of my device.

f same4 upon the line 2 2 in Fig. 1. Fig. 3-is a section somewhat similar to Fig. 2 and show@ ing another form of my device; and Fig. 4is a central section, otherwise similar to Fig. 1,

A leader -1 is mounted upon a wall 2 in l. the usual manner and is provided with an aperture 3, having the form o f a transverse slot, extending practically across the face of the leader. Mounted upon the leader and immediately adjacent to this aperture is a -box 4 of the shape shown and provided at its lower-end with a slanting plate 5, preferably integral therewith, the lower edge of the plate 5 being connected with the lower edge of the aperture 3, so that the box 4 virtually constitutes an ancillary short pipe connected directly with the leader. A bearing-plate 6 of the shape shown is rigidly secured upon Athe face of the leader 1 and is provided with a depending lip 7, which is spacedslightly shed in position. By slightly springing the Serial No. 152,887. (No model.)

lip 7 outward and bending the bottom of the posite the bead 11 when the shed is in itsV with that above described, with the exception that instead of the plate 6 (shown in Fig. 2') I use a strap 14, extending entirely across the face of the `leader and rigidly connected therewith. The top of the shed 15 instead of being provided with the upwardly extending lip 9, as in Fig. 2, is provided'with a downwardly-extending lip 16, which is merely slipped over behind the strap 14 as the shed 15 is brought down into place.

` In the form shown in Fig. 4 the leader'l, box 4, and screen 13 have the construction above described; but the shed 17 is permanently xed by soldering or otherwise upon the leader 1. `-'Ihelid 18 is provided with spring-tongues 19 20, which engage the shed 17 directly. 4To have access to the interior of the shed 17, the lid, 18 is simply removed somewhat after. the manner of a removable top of a milk-can, when the operator can look down into the box..

The general object of my Ventilator is to enable the interior ofV the leader to be-dried e quickly, thereby preventing damage to the sheet material of which the leader is composed.

l find that where a leader of sheet material is ventilated in the manner above described all moisture quickly dries out and the lifetime of the leader is thereby greatly prolonged.

Having thus described my invention, I claim as new and desire tosecure by Letters Patentf t l 1. Aventilatorforleader-pipes, comprising a pipe-section provided with an aperture,'a box disposed adjacent to said aperture and having a passage extending upwardly there- IOO from, and a' shed portion for said box, said shed portion being provided with an aperture opening downwardly.

2. Aventilatorforleader-pipes, comprising a pipe-section provided with an aperture, a

box mounted upon said pi pe-section and having a passage connected with said aperture and extending upwardly therefrom, and a shed portion connected with said box, shed portion beingprovided with an aperture opening downwardly.

3. A ventilator forleader-pipes, comprising a memberancillary to a leader-pipe and extend-ing upwardly therefrom,and a shed portion connected with said'leader-pipe a'nd with l'said member, said shed portion being so. disposed as to allow access to the interior of'said member.

4. Aventilator for leader-pipes, comprising a pipe-section provided with an aperture, a box mounted upon said pipe-section and dis posed ladj acent to said aperture, said box having a passage leading upwardly from said aperture, and a shed portion connected with said box.

5. Avcntilator for leadcr-pipes,'compri sin g said a leader-pipe section provided with'an, aperture,

leader-pipe and engaging said box, screen engaging said leader-box and said shed.`

6. Aventilatorforleader-pipes, comprising a leader-pipe section provided with an aper-4 ture, Vand disposed adjacent to said aperture, a strap mounted upon said leader-pipesection and spaced therefrom, and a shed engaging said box and provided with a portion for engaging said strap.' 1 v In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
